/* Define some macros for signal handling.  If USE_SIGPROCMASK is
   defined, we use the POSIX functions.  Otherwise we use the BSD
   functions.

   sigmasktype: type of mask argument to following macros.
   SIGBLOCK(MASK, SIG): block SIG, setting MASK to the old signal mask
   SIGBLOCK2(MASK, SIG1, SIG2): Like SIGBLOCK, but block both SIG1 and SIG2
   SIGBLOCK3(MASK, SIG1, SIG2, SIG3): Same again, but three signals.
   SIGUNBLOCK(MASK, SIG): unblock SIG, setting MASK to the old signal mask
   SIGSETMASK(MASK): set the signal mask to MASK

   These macros evalaute MASK multiple times.  */
